Subject: [PATCH v2 2/9] rcu: Mark rcu_dynticks_curr_cpu_in_eqs() inline

Precedence: bulk

Since rcu_is_watching() is notrace (and needs to be, as it can be
called from the tracers), make sure everything it in turn calls is
notrace too.

To that effect, mark rcu_dynticks_curr_cpu_in_eqs() inline, which
implies notrace, as the function is tiny.
